The positive electrode material of nickel-cadmium batteries is nickel hydroxide, the negative electrode material is cadmium oxide, and the electrolyte is potassium hydroxide. All three substances can be utilized as resources.

[0030] Cadmium and cadmium compounds in nickel-cadmium batteries are toxic and harmful, and are extremely harmful to the environment and human health. The main component of the electrolyte is potassium hydroxide, which is a strong alkaline and is also seriously harmful to the environment and human health. In the disassembly and classification process of waste nickel-cadmium batteries, it is necessary to prevent these toxic and harmful substances from leaking into the environment.

[0033] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The specific embodiments described below can be combined with each other to form new embodiments. The same or similar ideas or processes described in one embodiment may not be repeated in other embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0034] Figure 1 It is a schematic diagram of an embodiment of the battery disassembly equipment of the present application.

[0036] In this embodiment, the battery bottom plate cutting unit of the present application mainly cuts the bottom plate of the battery and then releases the electrolyte in the battery. Before cutting the battery bottom plate, the battery model is first detected to determine the position of the battery bottom plate, and then the battery bottom plate of the battery is cut using a cutting tool.

[0037] Optionally, the battery bottom plate cutting unit includes: a first detection device, which detects the external dimensions of the battery, determines the battery model, and locates the position of the battery bottom plate; a first clamping tool, which fixes the battery; and a first cutting tool, which cuts the battery bottom plate according to the position of the battery bottom plate to obtain a first battery part.

[0038] In this optional embodiment, the outer dimensions of the battery are detected by the first detection device in the battery bottom plate cutting unit, and then the size data of the battery obtained by the detection, such as the length, width and height data of the rectangular battery, are transmitted to the database for comparison of the outer dimensions of the battery. The database stores the outer dimension data of various types of batteries, and the battery model to be disassembled is determined by comparison. Then, according to the design specifications of the battery model, the position of the battery bottom plate is determined. Then, the battery is fixed by the first clamping tool, and then the battery bottom plate is cut by the first cutting tool.

[0039] Optionally, the first detection device includes: a laser, which detects the size of the battery from three directions to obtain the battery size, wherein the battery size is compared with the battery parameters stored in the database to determine the battery model of the battery.

[0040] In this optional embodiment, a laser is used as the first detection device to detect the external dimensions of the battery. The laser can emit laser light from three directions to measure the dimensions of the battery. For example, for a rectangular battery, the three directions of the laser correspond to the length, width and height. The measurement results are then compared with the battery parameters in the database to determine the battery model of the battery.

[0041] Specifically, different types of the first clamping tool can be selected. For example, pneumatic clamps can be selected to be arranged on both sides of the battery. After the battery is transported to the appropriate position, the transportation is stopped, and the battery is clamped by the pneumatic clamps on both sides for the subsequent battery bottom plate cutting process. After the battery bottom plate cutting is completed, the pneumatic clamp is reset, and the first battery part obtained after cutting will continue to be transported for the subsequent cutting process. The first cutting tool can be a hydraulic guillotine or a circular saw. The types of the detection device, the clamping tool and the cutting tool can be reasonably selected according to the actual requirements, and this application does not impose specific restrictions.

[0042] Figure 2 It is a schematic diagram of an embodiment of a battery bottom plate cutting unit of the present application.

[0043] like Figure 2 As shown, the battery 201 is transported to the battery bottom plate cutting unit by the transport device 203 , and then the battery bottom plate is cut by the first cutting tool 202 , and the electrolyte inside the battery flows out to the liquid receiving tray 204 .

[0044] exist Figure 1 In the illustrated embodiment, the battery disassembly equipment of the present application includes: an external terminal cutting unit 102, which receives the first battery part and performs detection and positioning, and cuts the exposed external terminals of the battery to obtain the second battery part.

[0045] In this embodiment, the battery has terminals for connecting to the outside, so during the disassembly of the battery, the exposed external terminals on the outside of the battery need to be cut off. In the external terminal cutting unit, the first battery part delivered is first detected and positioned to determine the position of the external terminals. Then, the first battery part is fixed by a clamping tool, and then the external terminals are cut to obtain the second battery part.

[0046] Optionally, the external terminal cutting unit includes: a second detection device, which detects and locates the first battery part to determine the position of the upper end cover of the battery; a second clamping tool, which fixes the first battery part; and a second cutting tool, which cuts the exposed external terminal according to the position of the upper end cover to obtain the second battery part.

[0047] In this optional embodiment, after the first battery part is transported to the external terminal cutting unit, the first battery part is detected and positioned by the second detection device to determine the position of the upper end cover of the battery, wherein the external terminal is located outside the upper end cover, thereby determining the position of the external terminal. Then, the first battery part is fixed by the second clamping tool, and the external terminal of the first battery part is cut by the second cutting tool to obtain the second battery part.

[0048] Figure 3 It is a schematic diagram of an embodiment of an external terminal cutting unit of the present application.

[0049] like Figure 3 As shown, the first battery part 302 reaches the external terminal cutting unit through the conveying equipment, and then the second detection device positions the first battery part, fixes it through the second clamping tool, and then uses the second cutting tool 301 to cut the external terminal to obtain the second battery part.

[0050] exist Figure 1 In the illustrated embodiment, the battery disassembly equipment of the present application includes: a non-electrode plate part cutting unit 103, which receives the second battery part, locates the position where the electrode plate and the terminal are connected in the second battery part according to the battery model, and cuts the non-electrode plate part in the second battery part to obtain a third battery part.

[0051] In this embodiment, inside the plastic shell of the battery, there are electrode plates and internal terminals connected to the electrode plates, that is, non-electrode plate parts, so in order to recycle the electrode plate parts, the electrode plate parts and non-electrode plate parts need to be cut and separated. In the non-electrode plate part cutting unit, the connection position of the electrode plate part and the non-electrode plate part is determined, and then the non-electrode plate part is cut to obtain a third battery part containing only the electrode plate part.

[0052] Optionally, the non-electrode plate part cutting unit includes: a third detection device, which detects and locates the received second battery part, and determines the connection position of the electrode plate and the internal terminal according to the battery model; a third clamping tool, which fixes the second battery part; a third cutting tool, which cuts the non-electrode plate part according to the connection position of the electrode plate and the internal terminal to obtain a third battery part.

[0053] In this optional embodiment, the delivered second battery part is detected and positioned by the third detection device, and then the position where the electrode plate and the internal terminal are connected in the battery, that is, the connection position between the electrode plate part and the non-electrode plate part, is determined according to the determined battery model. After the position is determined, the second battery part is fixed by the third clamping tool, and then the non-electrode plate part is cut by the third cutting tool to obtain the third battery part containing only the electrode plate part.

[0054] Specifically, in a nickel-chromium battery, the connection position of the electrode plate part and the non-electrode plate part is located 1-3 cm above the battery liquid level in the battery. Preferably, the cutting position is selected to be 2 cm above the battery liquid level. Cutting is performed according to this position to obtain the third battery part.

[0055] Figure 4It is a schematic diagram of an embodiment of a non-electrode plate portion cutting unit of the present application.

[0056] like Figure 4 As shown, the second battery part 402 is transported by a conveying device, and then the position is detected by a third detection device to determine the cutting position. Then, the second battery part is fixed by a third clamping tool, and the non-electrode plate part is cut by a third cutting tool 401 to obtain the third battery part.

[0057] exist Figure 1 In the illustrated embodiment, the battery disassembly equipment of the present application includes: an electrode plate part cutting unit 104, which receives the third battery part, separates the outer shell and the electrode plate part of the third battery part, and cuts the fixing belt of the electrode plate part in the third battery part to obtain a plurality of electrode sheets.

[0058] In this specific embodiment, in the electrode plate part cutting unit, the third battery part having only the electrode plate part is cut. First, the outer shell and the electrode plate of the third battery part are separated; and the fixing belt fixing the electrode plate is cut by a cutting tool, thereby obtaining electrode sheets separated from each other.

[0059] Optionally, the electrode plate part cutting unit includes: a fourth clamping tool, which clamps and fixes the third battery part; a pushing tool, which pushes the electrode plate part in the third battery part out of the outer shell; and a fourth cutting tool, which cuts the fixing belt of the electrode plate part to obtain multiple electrode sheets when the electrode plate part is clamped and fixed by the fourth clamping tool.

[0060] In this optional embodiment, in the electrode plate portion cutting unit, the third battery portion is clamped and fixed by a fourth clamping tool, and then the electrode plate portion in the third battery portion is pushed by a push rod tool to separate the electrode plate portion from the housing. Then, the electrode plate portion is clamped by a fourth clamping tool, and the electrode plate portion is cut by a fourth cutting tool to obtain an electrode sheet.

[0061] Optionally, the battery disassembly equipment of the present application also includes: an electrode sheet separation unit, which separates the positive electrode sheet and the negative electrode sheet in the electrode sheets, including: a conveyor belt, which conveys the separated multiple electrode sheets; a weighing machine, which weighs each electrode sheet separately, and separates the electrode sheets according to the corresponding weight ranges of the positive electrode sheet and the negative electrode sheet to obtain positive electrode sheets and negative electrode sheets.

[0062] In this optional embodiment, the electrode sheets in the battery are divided into positive electrode sheets and negative electrode sheets, wherein in order to better recycle the electrode sheets, the obtained electrode sheets are separated into positive electrode sheets and negative electrode sheets according to different polarities. When the electrode sheets are separated, the electrode sheets are conveyed by a conveyor belt, wherein the electrode sheets are not overlapped during the conveyor belt conveying the electrode sheets, and the electrode sheets are conveyed to a weighing machine. Then, the weight of a single electrode sheet is weighed by a weighing machine, and then the electrode sheets are classified according to the weight ranges corresponding to the positive electrode sheets and the negative electrode sheets to obtain corresponding positive electrode sheets and negative electrode sheets.

[0063] Specifically, the positive electrode sheet is usually 50-60 grams heavier than the negative electrode sheet. The weight difference between the two is used to classify the electrode sheets using a weighing machine.

[0064] Optionally, the battery disassembly equipment of the present application also includes: a conveying device, which includes multiple conveyor belts for conveying batteries between various cutting units, wherein the conveyor belts are inclined at a preset angle between the battery bottom plate cutting unit and the external terminal cutting unit.

[0065] In this optional embodiment, the battery disassembly equipment of the present application also includes a conveying device, which is used to transport the battery and transport the various parts of the battery after cutting to the corresponding cutting unit for subsequent processing. The conveyor belt in the conveying equipment is tilted at a certain angle between the battery bottom plate cutting unit and the external terminal cutting unit, so that after the battery bottom plate is cut, the electrolyte in the battery is discharged faster due to the tilt of the battery. In addition, in order to accelerate the discharge of the electrolyte, the operation of the conveyor belt can be stopped, and after a certain period of time, it can be restarted to give the electrolyte enough time to flow out. The inclination angle of the conveyor belt can be set to 3-5 degrees, preferably 4 degrees. The suspension time of the conveyor belt can be selected to be 10-15 seconds, preferably 13 seconds. In the actual operation process, the above values ​​can be reasonably selected according to the actual situation such as different battery models.

[0066] Specifically, in the conveying device of the present application, the conveying device includes not only the conveyor belt between each cutting unit, but also the roller conveying part in the cutting unit.

[0068] In this specific embodiment, the loading unit is a battery storage area, and batches of batteries are transported to the loading unit and then transported to the cutting unit for battery cutting. In the process of transporting the batteries to the battery bottom plate cutting unit, the battery can be clamped into the battery bottom plate cutting unit by a robot arm for battery cutting.

[0069] Specifically, the battery bottom plate cutting unit, the external terminal cutting unit and the non-electrode plate cutting unit of the present application are also provided with chute mechanisms, respectively. They receive the cut battery bottom plate, external terminal and non-electrode plate respectively. In addition, a vibration device is also provided in the non-electrode plate cutting unit to vibrate the cut non-electrode plate in the chute mechanism, so that the metal and plastic of the non-electrode plate are separated for easy recycling.

[0070] Specifically, a fan is provided in the electrode plate cutting unit. In the electrode plate, there is a separator between the positive electrode sheet and the negative electrode sheet. The fan blows air on the separator to separate the separator from the electrode sheet, which is convenient for recycling the electrode sheet.

[0073] Figure 6 It is a schematic diagram of an example of the battery disassembly equipment of the present application.

[0074] like Figure 6 As shown, after obtaining the electrode plate part, the electrode plate is pushed out of the housing using a push rod tool to obtain the electrode plate as shown in FIG. Figure 6 The electrode plate shown in FIG. includes each electrode sheet 601 and a fixing belt 602. In the electrode plate partial cutting unit, a fourth clamping tool is used to fix the electrode plate, and a fourth cutting tool is used to cut the electrode plate along the electrode sheet. Figure 6 The fixing tape is cut as indicated by the letter D to obtain individual electrode sheets.

[0075] Figure 7 It is a schematic diagram of an example of the battery disassembly equipment of the present application.

[0076] like Figure 7 FIG. 1 is a schematic diagram of an example of an external terminal cutting unit or a non-electrode plate portion cutting unit. Figure 7 In the figure, on the workbench 712, the saw blade 705 is used as a cutting tool and is controlled by the asynchronous motor 703 and the transmission device 704. The two are fixed together on the ball screw 702, and the rotation of the screw is controlled by the servo motor 701 to adjust the height of the saw blade. The ball screw is set on the vertical guide rail 710. During the battery cutting process, the delivered battery is fixed in position by the battery clamping tool 708, and the battery positioning baffle 709 is controlled by the electric push rod 711 to adjust the position of the battery, thereby ensuring the accuracy of the battery cutting position. After the battery is cut, the suspension rod 707 set on the horizontal guide rail 706 drives the battery clamping tool to move and no longer clamps the battery. The saw blade and the battery positioning baffle are reset, and the cut battery is transported to the next unit.
